eve online 4s

In EVE Online, the 4S (or 4-S) typically refers to the 4-Spectrum Shield Hardener, a module used to improve shield resistance against all four damage types: Kinetic, Thermal, Explosive, and EM. Key Details About the 4-Spectrum Shield Hardener: Effect: Provides balanced resistance boosts (usually around 2025% per damage type) but is less effective than specialized hardeners (e.g., Kinetic Shield Hardener for pure Kinetic resistance). Usage: - Useful in PvE (e.g., missions, ratting) where incoming damage types are mixed. - Less optimal in PvP, where pilots prefer specific hardeners to counter expected damage. Meta Variants: - Named variants (e.g., "Enduring", "Compact") offer better fitting or efficiency. - Deadspace/Officer variants (rare) provide stronger bonuses. Fitting: - Requires medium slot and capacitor to run. - Often used on shield-tanked cruisers, battlecruisers, or battleships. Alternate Meaning: "4S" as a Location Some players refer to "4S" as a system (e.g., 4S-SIG in Delve during the Goonswarm era). Always check context4S as a module is far more common. Should You Use It? Yes for general PvE where damage types are unpredictable. No for min-maxed PvP fits (use dedicated hardeners instead). Would you like fitting examples or comparisons with other hardeners?
